MILLER MAOHIN, OF BOIVEN, ILLINOIS, ASSIGNOR OF ONF-HALF TO DAVID S. ADAMS, OF SAME PLACE.

1 HAY-STACKER.

SPECIFICATION forming part of Letters Patent No. 447,250, dated February 24, 1891.

Application filed July 12, 1890. Serial No. 358,487. (No model.)

' be readily set up in a field to stack the hay,

or attached to barracks or to a barn to place the hay therein.

The invention consists of a pivoted arm provided with a head carrying a pivoted i 5 catch, a tripping-lever adapted to engage the said head and pivoted on the free ends of connected levers.

The invention also consists in certain parts and details and combinations of the same, as

willbe described hereinafter,and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate 2 5 corresponding parts in all the figures.

Figure l is a side elevation of the improvement as applied to a barn, which is shown in section. Fig. 2 is a front view of the same in its uppermost position. Fig. 3 is an enlarged sectional side elevation of part of the improvement, and Fig. 4 is a similar view of the same in a different position.

The improved hay-stacker A can be readily applied to a barn B, as illustrated in Figs. 1

5 and 2; or it may be applied to a number of stacking-poles set in the usual manner on the ground and fastened together near their upper ends. When the device is applied to a barn, the latter is provided in its roof with hinged doors B, which, when opened, form an opening for the entrance of the hay to be deposited in the barn by the device.

On the ridge-pole B of the barn B is pivoted in about the middle of the roof-opening,

an arm D extending outward a suitable distance beyond the side of the barn, as is plainly shown in Fig. 1. On the outer end and on the under side of the arm D is formed a head E, adapted to be engaged by the fulcrum end of a tripping-lever F, pivoted on atransversely-extending rod G, secured in the free ends of levers H, pivoted at their lower ends on the roof of the barn and at the sides of the doors 1%, as is plainlyillustrated in Fig. 2. The outer ends of the levers H are connected with each other by a yoke I, adapted to pass over the arm D and to rest thereon when the fulcrum end of the tripping-lever F engages the head E and hangs in its normal position, as illustrated in Fig. 3.

On the rod Gr is pivoted a downwardly hanging U-shaped arm J, carrying a pulley K, and on the said rod is also fastened one end of a rope L, extending downward and passing under a pulley N of the head-block of ahay-fork N, of the usual construction, and adapted to carry the hay from the wagon into the'loarn or onto the stack. The rope L, after passing under the pulley N, extends upward and passes through the forked end F of the tripping-lever F, and then passes over the pulley K, and from there extends inward below the arm D to pass over a pulley 0, held on the under side of the ridge-pole B near the pivoted end of the arm D. The rope then passes from the pulley 0 over apulley P, arranged at the lower end of the root, and then extends downward and passes under a pulley Q, mounted to turn in suitable bearings secured to the barn-floor, so that the rope then extends about horizontally to be attached to a pulling-gear for a horse or other animal or mechanical device for actuating the stacking device.

In the free end of the arm D, near the head E, is arranged a vertical slot, in which is pivoted a catch R, made in L shape, and adapted to be engaged by the straight part F of the tripping-lever F. The catch is provided on its free upper end with a head R, adapted to rest on the top of the arm D, so as to limit the downward movement of the said catch, the lower projecting corner R of the said catch being adapted to lock the tripping-lever F in place, as is shown in Fig. 3. 5

The operation is as follows: \Vhen the de vice is in the position shown in Figs. 1 and 3, the rope L, with the fork N, extends down ward, so that the operator can engage the fork N in the hay on the wagon, the animal 10:) for pulling the rope L being backed up near to the barn. hen the fork N is inserted in the hay, the animal is started forward, so as to exert a pull on the rope L, whereby the forkN is raised, as the end of the rope is fastened to the rod G, as previously described. \Vhen the head-block of the fork N strikes against the under side of the curved forked end F of the tripping-lever F, a further upward motion of the said fork N is prevented, and a further pull on the rope L now causes the tripping-lever to swing upward, whereby the catch R is moved upward by the straight part F of the said tripping-lever, and the levers H are thus unlocked from the arm D. The levers H by a further pull on the rope L now swing upward and inward, carrying along the filled fork, at the same time swinging the pivoted arm D upward, the fulerunied end of the tripping-lever F traveling on the under side of the arm D. The levers H finally pass into about a vertical position, so that the fork N is suspended in the opening of the roof; and when the operator now backs up the animal the rope L, supporting the fork LT, moves downward and the filled fork passes into the barn, so that the hay is deposited therein on opening the fork. As soon as the fork is empty, the weight of the arm D will cause the levers II to swing outward again into their normal position, as shown in Fig. 1. The fork N is then free again to descend 011 the rope L to be again filled from the wagon. The abovedescribed operation is then repeated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a haystaeker, the combination, with a pivoted arm having a head, of levers connected at their free ends by a transverse rod arranged at the under side of the said pivoted arm, a rope secured by one end to the said transverse rod and adapted to pass over a pulley suspended from the said rod and also adapted to support the hay-fork, a tripping-lever fulcrumed on the said transverse rod, and a catch pivoted on the said arm and adapted to lock the said tripping-lever in place, substantially as shown and described.

2. In a hay-stacker, the combination, with a pivoted arm having a head, of levers connected at their free ends by a transverse rod arranged at the under side of the said pivoted arm, a rope secured by one end to the said transverse rod and adapted to pass over a pulley suspended from the said rod and also adapted to support the hay-fork, a tripping-lever fulcrumed on the said transverse rod and adapted to rest with its fulcrnmed end against the head of the said arm,it being also provided with a curved slotted end adapted to be engaged by the hay-fork, and the catch pivoted on said arm, substantially as shown and described.

3. In a hay stacker, the combination, with connected levers, of a tripping-lever fulcrumed in the free end of the said connected levers and provided with a curved forked arm, a pulley suspended from the pivot of the said tripping-lever, a rope secured at one end to the pivot ot' the said tripping-lever and adapted to support a hay-fork and also passing over the said pnlley,a pivoted arm resting with its under side on the pivot end of the said tripping-lever, and an L-shaped catch pivoted on the said arm and adapted to lock the said tripping-leverin place, substantially as shown and described.
